Through the Strengthening the Army Through the Reserves (StAR) project, it will be assigned a mission task,[14] which is still in the analysis stage, to acquire chemical, biological, radiological and nuclear (CBRN) detection expertise.

Currently validated missions include force protection, convoy escorts, Arctic response company groups, and territorial battalion groups; newly identified missions like infantry platoons, reconnaissance, direct fire support, assault pioneers, mortars, influence activities, persistent surveillance system, and long-haul trucking; and exploring future missions such as assault troop, light urban search and rescue, light engineer bridging, cyber threats.

The guidon of The Sherbrooke Hussars has, at its centre bottom, the device of the Royal Rifles of Canada[26] to denote the honorary distinction battle honour for Hong Kong.

A later draft saw another 165 men transferred to the 5th CMR giving them some solace in serving with a somewhat homegrown battalion, and they were initiated into the front lines by the end of January 1917.

The left forward company of the 5th CMR managed to reach the objective also, established a blocking position, but were driven out early on the morning of 2 October by continuous counter-attacks.

The British achieved the longest advance since trench warfare had begun, surpassing the record set by the French Sixth Army on 1 July 1916.

Passchendaele lay on the last ridge 5 mi (8.0 km) from the railway junction at Roulers, which was an important part of the supply system of the German 4th Army.

The main German positions were anchored on the so-called Hindenburg Line, a series of defensive fortifications stretching from Cerny on the Aisne river to Arras.

The objective was to break through one of the most heavily defended stretches of the German Siegfriedstellung (Hindenburg Line), which in this sector included the St. Quentin Canal as part of its defences.

The assault achieved its objectives (though not according to the planned timetable), resulting in the first full breach of the Hindenburg Line, in the face of heavy German resistance.

Together with the American forces breaking out of the forests of Argonne, the attack disrupted German efforts to reform a shortened defensive line along the Meuse.

Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France.

Entrenchments, machine gun emplacements, barbed wire and artillery repeatedly inflicted severe casualties during attacks and counter-attacks and no significant advances were made.

1 General Base Depot, Canadian Active Service Force, on 1 September 1939, which embarked for Britain on 25 January 1940 where it provided guards for vulnerable points until disbanded on 6 July 1940.

Commanders paid close attention to medical standards to remove soldiers and officers who were unfit or unlikely to fully recover from accidents or illness.

Similar to the expectation on the soldiers and officers to excel, there was command pressure on the unit to form into a competent functioning and efficient fighting regiment.

Virtually nonstop visits, inspections, testing, competitions, training courses and schools, and interminable exercises drilled the lessons into all ranks.

Its open spaces, overgrown farm fields, sand pits, brush and forested areas provided excellent off-road opportunities for trainee drivers.

Over the years many Basic Training courses dug defensive trench lines and waited in the gloom of dawn to repel blank-firing attacks, and practised compass marches through the swamps.

The question of maintenance on the William Street Armoury was asked of Prime Minister Justin Trudeau during his town-hall visits in January 2017.

[66] The outgoing commanding officer, Lieutenant Colonel L-B Dutil, said that moving the four regiments to the Belvedere Street Armoury was unlikely to proceed, "With the growth of the reserves, with the new vehicles that have arrived, and with other factors, it means that this option may not be the best, ... (translated from French)."

Minister Anand stated the Department will work with heritage consultants and the City of Sherbrooke to restore the William Street Armoury in a manner that preserves its historical value.
